Acid production in milk was, as might be expected, closely 

 correlated with acid production in lactose broth as shown by- 

 table 6. 



TABLE 6 



Reactions in milk compared with reactions in lactose broth 



TABLE 7 

 Gelatin liquefaction corn-pared with liquefaction of casein 



TABLE 8 

 General grouping of staphylococci studied 



The liquefaction of casein was correlated to some extent, but 

 not very closely, with the liquefaction of gelatin as shown in 

 table 7.
